3 Claims.

This invention relates to knitting machines with special reference tothe verge plates used in connection with the sinkerhead or loop formingdevices for straight line knitting machines.

Among the several objects the more important are: in reducing strain ofthe mechanism, preventing undue wear; avoiding jack, sinker and wornplate lines in the fabric; preventing uneven knitting, and effectingvery considerable l0 saving of sinkers, time and material.

More specifically the purpose of the invention is in the provision of a,verge plate limitedly movable and resiliently pressed outward away fromthe sinker plate.

These objects are accomplished by the n ovel construction andarrangement of parts hereinafter described and illustrated in theaccompanying drawings, constituting an essential component of thisdisclosure, and in which:-

l2l) Figure 1 is a top plan view of the sinker head of aconventional-type of knitting machine showing an embodiment of theinvention in opera.- tive position.

Figure 2 is a plan view of the verge plate in detail.

Figure 3 is a similar view of the sinker plate.

Figure 4 is an edge view of undulating spring interposed between theverge and the sinker plates.

Figure 5 is a front elevational view of the same.

Figure 6 is an enlarged transverse sectional view taken on line G--B ofFigure l.

Figure 7 is a similar sectional view taken on line 1--1 of Figure 1.

Figure 8 is a transverse sectional view of the loop forming portion ofthe knitting machine.

Figure 9 is a similar sectional view showing the same parts in advancedposition.

4,0 Figure 10 is another like view of the same as further advanced.

Referring in further detail to the drawings, the machine will be seen toinclude a frame composed of a center bed I5 extending the length 4.3 ofthe machine; on the rear flanged portion of the bed is secured a jackbed I6, and on top of its upright forward portion is a base bar I1, itslateral edges extending both forwardly and rearwardly as shown.

The bar I'l is plurally grooved transversely to slidably receivedividers I8 alternating with sinkers I9, the upper edges of theseelements being engaged in corresponding grooves in the cap bar 20 of thesinker head.

56 Raised lugs 2| on the dividers I8 are engaged in a catch bar 22 by anadjustable block 23 attached to cam actuated arms 24 moved rectilinearlyby the machine elements. (Not shown).

Carried adjustably on the jack bed I6 are a series of spacer members orjack combs 25 held by a clamp bar 25 and spaced in conformity with thesinkers I9 whereby alinement is maintained.

A plurality of jacks 2l are pivoted on a rod 23 set in the spacers 25and pressed forwardly by individual springs 29, their motion beinglimited by a stop bar 30.

The upper, forwardly curved ends of the jacks 21 are adapted to contactupstanding projections 3| at the rear ends of the sinkers I9.

A plurality of needles 32 are secured in a needle bar 33 held by a clamp34 therein and actuated in a manner well known in the art.

'I'he improvements consist in a novel form of verge plate 35 looselyheld on the inclined upper surface of the cap bar 20 of the sinker headand floatingly secured against rising by shoulder screws 35.

The verge plate is provided with substantially triangular openings 31near its ends, through which extend pins 3Il xed in the cap bar 20.

'I'he rear edge 39 of the plate 35 is downwardly flanged and positionedin spaced relation to the rear edge of the cap; in the space thus formedis inserted a thin flat spring 40, bent sinuously to produce a series ofundulations 4I, and its ends 42 turned angularly, its effect being tonormally press the verge plate 35 rearwardly when it strikes the sinkerprojections 3|, cushioning the contact.

Thus the constant pounding of the sinkers is minimized, reducing wearand vibration and distributing the shock to the machine.

As changes of construction could be made within the scope of theinvention, it is intended that all matter contained in the foregoingdescription or shown in the accompanying drawings shall be interpretedas illustrative and not in a limiting sense.

Having thus described the invention, what is claimed as new and desiredto secure by Letters Patent, isz- 1. In a knitting machine having asinker head provided with a cap bar and a plurality of divider andsinker elements movable transversely in grooves therebetween, saidsinkers having raised projections rearwardly of the cap bar, a verge barfloatingly secured on said cap bar, said plate having a. down-reachingflange entering the space between said b ar and projections, and a flatspring plurally undulated interposed between said flange and cap bar.

2. In a knitting machine having a sinker head provided with a cap barand a plurality of divider and sinker elements movable transversely ingrooves cooperatively formed therein, a verge plate having triangularopenings, pins set into said head to extend into the mentioned openingslimiting the movement oi said plate, means to prevent rising of saidplate, a down-reaching ilange on said plate spaced from said cap, andresilient means disposed in the space therebetween to cushion the impacto! said sinkers.
